This is the most recent patch for the game: http://dominagame.com/updates/DOMINA(v1.3.28)(EXECUTABLE-ONLY).zip
It contains only the executable (no resources were updated) and should give you access to all DLC. Steam doesn't want you to have this and they remove it every time we post it in the official steam forum. We don't know why.
Simply copy the executable file into your DOMINA installation directory and run it. If you have problems, please Contact Tech Support
Thank you for your continued support during these dark times.
